A peer-to-peer (P2P) system consists of a number of decentralized distributed network nodes that are capable of sharing resources without centralized supervision. One of the most important functions in P2P system is locating resources. Dynamic joins and leaves of the node and heterogeneous network structure in a P2P system make it difficult to discover shared resources. We present a multi-agent approach for resource discovery in P2P systems. Agents maintain local resource information and mobile agents migrate on the network to discover shared resources. Empirical results verify that the be reduced greatly, ans scalability and robustness can also be improved.
